Exactly. :-)

The FAQ does adresses the question, but it gives almost no information as
to why the two groups split up. Did they disagree about some Loglan feature? Was
it about the way the Loglan Institute was being run?

Also, I would like to know what are the differences between Loglan and
Lojban as to linguistics.

I agree with Robin when he says that Esperanto is a "mushing of European
languages". It is kind of arrogant that it tries to pass itself as the "solution
to the language problem". That's what caught my attention at first about Lojban:
it is "more neutral" than Esperanto, Ido, Interlingua, Glosa and others.

By the way, I'd like to congratulate Robin and Nick about their great
introduction to the language! :-)
